Can we have a little more context for the question please? Utility
for what purpose?
GLMs (generalized linear models) don't have grouping structure at
all, so the terms "within-group" and "between-group" don't really
(G)LMMs summarize "among-group variance" as the variances of the
random effects. "Within-group variance" is the residual variance for a
linear mixed model (LMM, i.e. a GLMM with Gaussian response and
identity link), harder to compute for non-LMM GLMMs (but papers e.g.
by Nakagawa and Schielzeth define these components on the way to
estimating R^2 or intra-class correlation values for GLMMs).
